@mactunag Sadly it isn't.
But we also didn't help ourselves. I had a client who brought in a new manager. I explained a little about our background and my heart sank as he went "Open Source right". It was the tied tone of someone who'd been evangelised at and wasn't ready to listen. I fully expected at that point to lose the client.
Thankfully I turned that relationship around. By being helpful and carefully never mentioning the software. Easier when you're providing an IMAP service.
